Abstract (en)
Apparatus for sintering a hollow cylindrical body (1) of porous synthetic silica comprises a hollow mandrel (2) for supporting the body in a horizontal position. The mandrel is housed within a vacuum furnace (5) having heating elements (4) arranged to surround the body circumferentially along its entire length. A method of sintering a hollow cylindrical body (1) of porous synthetic silica is also disclosed.
